Repeat the first stroke and the second stroke so that the turbine can continue to do work.

Compared with the prior art, the present invention has the following advantages:

1. In the present invention, the power cylinder is provided with a power fluid cavity, a lubrication and heat dissipation fluid cavity, a power air cavity and an I-shaped piston, the liquid oil is used as a medium for transferring energy, and the small area of the second piston plate of the I-shaped piston is affected by All the pressure is transmitted to the large-area second piston plate, which greatly reduces the pressure in the power fluid chamber, converts the internal energy of the high-temperature and high-pressure gas into a working condition suitable for the operation of a liquid turbine, and maintains a 90-degree equivalent to a high-efficiency hydraulic turbine. % Efficiency and high energy efficiency than rotating output.

The exhaust gas temperature is reduced and the working temperature in the power cylinder is reduced, thereby reducing energy loss and providing necessary conditions for improving the utilization rate of internal energy.

2. There are multiple power components in the present invention, and the activation of each pair of power cylinder components can be activated according to power requirements. The flow rate of the liquid is used to control the turbine to transfer energy. Therefore, the power components in the present invention have their own The attribute of the torque converter can automatically output power consumption within a certain range, which is convenient for use under changing conditions, so it can further reduce fuel consumption, and at the same time, there is no need to entangle the placement of the engine during installation.

3. The number of power cylinder components in the present invention can be set according to power requirements, so sufficient power can be provided in a larger power range, so the scope of application is wide.

4. Compared with gaseous direct drive turbines for steam turbines and gas turbines, the present invention adopts an I-shaped piston structure in the power cylinder, which can better improve the resistance of the power cylinder to the temperature and pressure of high-temperature and high-pressure gas, and can also greatly reduce The difficulty of the process is a favorable condition to improve the efficiency of the heat engine; it is convenient to adjust the size of the power cylinder and the logarithm of the power cylinder according to the requirements of the working conditions to meet the needs of different equipment and avoid the high technical threshold of similar super large steam turbines. It is difficult to maintain, and the gas expansion is insufficient during miniaturization and the efficiency is low.

5. Compared with the internal combustion engine, the present invention adopts the method of liquid thrusting turbine to transfer energy. The non-rigid connection of the liquid completely gets rid of the linkage restriction between the connecting rod and the crankshaft. The power cylinder can achieve high temperature and high pressure under the control of the intake valve and the exhaust valve. The gas obtains a sufficiently large expansion ratio, which greatly reduces the working temperature of the power cylinder and the exhaust gas discharge temperature, greatly reduces the energy loss in the cylinder body and the exhaust gas, and improves the efficiency of the whole machine. The front end of the intake valve adopts an air compressor to press air into the combustion chamber and mix and burn the fuel to generate high-temperature and high-pressure gas, which is then introduced into the rectifier liquid turbine to perform external work. This separation of combustion and work is feasible. Similarly, it is possible to separate air intake and fuel injection. The nozzles and spark plugs are added to the power cylinder to become the working mode of the internal combustion engine, but it is different from the traditional internal combustion engine in that it is very convenient to obtain different compression ratios and expansion ratios through the adjustment of the valve to adapt to different Output working conditions, thereby improving efficiency.

6. In daily life, internal combustion engines are most commonly used in automobiles, while automatic transmission vehicles are most commonly used in AT gearboxes. On the other hand, AT gearboxes consume more fuel than CVT gearboxes and DCT gearboxes, mainly due to the planetary gears of AT gearboxes. There is the loss of the hydraulic torque converter of the hydraulic oil transmission before, and the rectifier type hydraulic turbine of the present invention itself has the attribute of the hydraulic torque converter, which can be directly connected to the planetary gear with variable speed without the hydraulic torque converter. Coupled with the support of the variable compression ratio and expansion ratio in the cylinder of the rectifier liquid turbine, the fuel consumption will inevitably decrease.

The turbine is installed in the hydraulic cylinder through the main shaft, and the turbine connects the hydraulic cylinder to the hydraulic cylinder. The inner cavity is divided into an oil inlet cavity and an oil outlet cavity. The power cylinder assembly includes a power cylinder and an I-shaped piston. The I-shaped piston divides the power cylinder into three power chambers. The three power chambers are power fluid chambers. , Lubricate the heat dissipation fluid cavity and the power air cavity, the outlet of the power fluid cavity is connected to the oil inlet cavity through the first oil pipe, and the inlet of the power fluid cavity is connected to the oil outlet cavity through the second oil pipe; in the same pair of power cylinder assemblies The two lubrication and heat dissipation liquid chambers are connected by a third oil pipe to form a lubrication and heat dissipation liquid flow loop. The power air chamber is provided with an intake valve and an exhaust valve. The first oil pipe and the second oil pipe are both provided with Opposite solenoid valve.

At the same time, the first oil pipe and the second oil pipe are equipped with opposite solenoid valves, so that the opening and closing of the first oil pipe and the second oil pipe have a linkage effect, and the reliability of the work is further improved. In order to further improve the heat dissipation effect of the lubricating heat dissipation liquid cavity, the third oil pipe is connected to the second radiator.

The power cylinder includes a main body cylinder and an auxiliary body cylinder with a smaller section than the main body cylinder. The main body cylinder is connected to the auxiliary body cylinder.

This structure is simple and convenient for manufacturing and installation. Specifically, the I-shaped piston is mainly composed of a first piston plate, a second piston plate and a connecting rod. Because the area of the first piston plate is larger than that of the second piston plate, the first piston is connected to the second piston plate through the connecting rod. Form an I-shaped piston with an I-shaped structure. During the working process, when high-temperature and high-pressure gas enters the power gas chamber, the high-temperature and high-pressure gas exerts pressure on the second piston plate with a smaller area, thereby driving the large-area first piston plate to move toward the inner end of the power fluid chamber (that is, near the ferry).

The iris-type liquid flow rate adjusting ring can control the flow rate of oil into the oil inlet cavity, and the pressure sensor can monitor the hydraulic pressure in the oil inlet cavity in real time. This uses the combination of an iris-type liquid flow rate adjustment ring and a pressure sensor, which can precisely control the speed of the oil flowing through the turbine, so as to ensure that the power meets the output requirements.

A displacement sensor for detecting the I-shaped piston is arranged in the power fluid cavity. The displacement sensor is used to detect the activity of the I-shaped piston in real time to confirm whether the I-shaped piston is operating normally.

Specifically, in the first stroke, the I-shaped piston in the first power cylinder drives the liquid oil to be pressed out from the power fluid chamber in the first power cylinder, and then from the first oil pipe, the oil inlet chamber, the oil outlet chamber, and The second oil pipe and the power fluid chamber in the second power cylinder, the liquid oil pushes the turbine to do work during this flow; and in the second stroke, the I-shaped piston in the second power cylinder drives the liquid oil from the second power cylinder After the inner power fluid cavity is pressed out, and sequentially from the first oil pipe, the oil inlet cavity, the oil outlet cavity, the second oil pipe and the power fluid cavity in the first power cylinder, the liquid oil pushes the turbine to do work during this flow. As a result, the liquid oil circulates and reciprocates between the power fluid chamber pressure in the first power cylinder, the first oil pipe, the oil inlet chamber, the oil outlet chamber, the second oil pipe, and the power fluid chamber in the second power cylinder. , In order to push the turbine to do work. In this process, liquid oil is used as a medium to transfer the energy of high-temperature and high-pressure gas to the turbine by means of hydraulic transmission and convert it into mechanical energy, thereby improving the utilization rate of energy.
